The electrochemistry of real gold ore processing wastewater solutions from copper sulfide containing gold ore has been investigated. Analysis shows that the wastewater contains a range of sulfur compounds in various oxidation states from sulfide to sulfate. The electrochemical characteristics of...

In the present work the modes of four-legged locomotion generated and controlled by a network of coupled electrochemical oscillatory electrode pairs are explored. Each pair, operating under constant potential conditions, consists of an iron disk (anode) and a copper coil (cathode) and all pairs...

Presents a study which examined the electrical properties of InP/Au dry contacts and the influence of electrodeposited gold on the electrochemical properties of indium phosphide electrodes. Experimental details; Results; Conclusions.

A composite film containing a heteropolyanion was prepared on a 2-aminoethanethiol (AT) self-assembled monolayer film-modified gold electrode by attaching the Keggin-type phosphomolybdic anion. The surface structures and electrochemical properties of the composite films were characterized by...

Granular nanowires with a diameter of about 60 nm were fabricated from cuprous oxide (CuO) by an electrochemical method using anodic aluminium oxide as the template. A non-enzymatic sensor for hydrogen peroxide (HO) was then developed on the basis of a gold electrode modified with CuO nanowires...

Micro-nano structured Cu-Co was in situ fabricated on the surface of a gold electrode via electrochemical reduction of CuCl and Co(NO). It is shown that the shape of the particles can be controlled by variation of deposition current, deposition time, pH value and the ratio of Cu(II) and Co(II)...

A penicillamine (PCA) self-assembled monolayer (SAM) was prepared on a gold electrode. It has been found that the modified electrode exhibited a selective response to copper ions. As demonstrated by cyclic voltammetric experiments, the SAM-based electrode showed an attractive ability to...

The suitability of various dimensionally stable anodes (DSAsÂ®) was investigated in comparison to the conventional lead alloy anodes in the electrowinning of copper. DSAÂ® plate and mesh specimens of composition Tiâ€“(70%) IrO2/(30%) Ta2O5 and leadâ€“(6%) antimony were evaluated....
